Fix Savannah bug #106: keep separate track of which variable we are expanding, and use that info when generating error messages instead of the file info, where appropriate.

Directly handle $\ line endings Previously we used the fact that this line ending expanded to "$ " which would then expand to the empty string. This has problems if you enable warnings for undefined variables, so directly implement this special (but documented) trick in the GNU Make parser. As a side-effect this also removes all previous whitespace when in GNU Make mode (not in POSIX mode) just as it would without "$". * src/misc.c (collapse_continuations): Check for "$\" and remove it. * tests/scripts/variables/flavors: Add regression tests including with previous whitespace, and escaped/unescaped "$"

Add support for the POSIX :::= assignment operator. POSIX Issue 8 will require a new assignment operator, :::=. This operator behaves similarly to the BSD make := operator: the right-hand side is expanded immediately, but then the value is re-escaped (all '$' are converted to '$$') and the resulting variable is considered a recursive variable: the value is re-expanded on use. * src/variable.h (enum variable_flavor): Add f_expand flavor. * src/variable.c (do_variable_definition): When defining f_expand, post-process the result to re-escape '$' characters. Remove default: to the compiler warns about un-handled enum values. Set recursive values for both f_recursive and f_expand. (parse_variable_definition): Rewrite this method. The previous version was annoying to extend to ':::='. (print_variable): Remove default: so the compiler warns us about un-handled enum values. * src/function.c (func_origin): Remove default: so the compiler warns us about un-handled enum values. * doc/make.texi: Add documentation for :::=. * tests/scripts/variables/define: Add a test for define :::=. * tests/scripts/variables/flavors: Add tests for :::=. * tests/scripts/variables/negative: Add tests for :::=.
